Earl's Ano-Tuff Swivel-Seal Hose Ends are precision machined from aluminum with a distinctive, bright dipped black, military spec hard anodizing. This recently developed hard anodizing process adds superior wear and corrosion resistance to aluminum at a reasonable price. The Ano-Tuff coating penetrates the aluminum to create a surface that lasts twice as long as traditional anodizing. !

Note: Earl's Ano-Tuff Swivel-Seal Hose Ends are designed for use with Earl's Perform-O-Flex, Pro-Lite 350, Pro-Lite Ultra, and Auto-Flex Hose.
